Description
Technical field
This utility model relates to a kind of fracture anatomy locking External technique field, specifically a kind of extremity length bone fracture anatomy locking extenal fixation frame plate system, can close or compound fracture adult, teenager, the long and short tubular bone of child's extremity, carry out external fixing fixed system.
Background technology
Extremity fracture can be divided into closed fracture and compound fracture by the integrity of skin.Can fix or Intramedullary nailing by row open reduction titanium plate after extremity repercussive for closed fracture.After union of fracture, second operation takes out internal fixtion; The feasible debridement of compound fracture, reset, external fixer are fixed, the feasible Kirschner wire fixation of brothers, and after soft tissue improvement of terms, replaceable titanium plate is fixed or Intramedullary nailing (or not changing fixing), and the later stage removes fixing according to union of fracture situation.Current selectable external fixer comprises: external fixation devices, combination external fixer etc.The feature of these external fixers can be summarized as: 1. each fracture segment can put nail limited amount, and fixing imprecise, the broken ends of fractured bone is unstable; 2. profile and volume are too large, and be inconvenient to nurse, patient easily produces fear; 3. later stage nonunion rate is high, often need to wait soft tissue from open become closed after change internal fixtion.Also have scholar to report with locking titanium plate external treatment fracture of tibia and fibula, but also have the following disadvantages: 1. because screw used is full thread, to skin and other soft tissue irritation violent, easy infection.2. titanium plate and screw are originally for internal fixtion designs, thin small and exquisite, titanium plate thickness, short of width, and the thinner mechanical strength of screw is not enough.3. non-expert external design, needs polylith titanium plate to fix sometimes.
Summary of the invention
The purpose of this utility model is to provide a kind of extremity length bone fracture anatomy locking extenal fixation frame plate system, needs second operation to take out internal fixtion after can overcoming extremity long and short bone closed fracture internal fixation operation; After the existing external fixer of compound fracture is fixing, disunion rate is high, usually needs secondary to change the prior art defects such as internal fixtion.
The technical solution of the utility model is that extremity length bone dissects locking extenal fixation frame plate system, comprise mate with screw on locking extenal fixation frame plate sight, with the screwdriver of screw mates, and the dipstick of screw mates; Also comprise the screw that locking extenal fixation frame plate, locking extenal fixation frame plate mate with screw;
Described locking extenal fixation frame plate, its shape, length, width coordinate with the anatomical surface of fracture, plate are furnished with multiple locking screw; Between locking screw, gap location is provided with or is not provided with kirschner pin hole, is provided with one or more pressurization screw or is not provided with pressurization screw;
The described screw mated with locking screw, rivet nut is divided into three sections, is respectively nose threads section, stage casing polished rod section, threads section; Threads section is mated with locking screw.
Further, described locking external fixer plate thickness is within the scope of 0.1-4.0cm, and external fixer plate thickness is homogeneous; Or extenal fixation frame plate centre thickness is the thickest, and outside edge is thinning gradually
.
Further, described locking screw, screw is towards being multi-angle.
Further, described screwhole diameter 0.1 ~ 2.5cm, screw spacing 0.2 ~ 10.0cm.
Further, described plate is furnished with multiple locking screw, refers to that locking screw is distributed in a line or multirow or random distribution.
Further, the described screw mated with locking screw is self tapping or non-tapping screw, front end threaded section diameter 0.1 ~ 1.5cm, length 0.2 ~ 15cm; Stage casing polished rod partial-length 0.5 ~ 20cm, diameter 0.1 ~ 1.0cm; Threads mates with screw screw thread, the length >=0.1cm of threads ,≤2.5cm.
Locking extenal fixation frame plate length of the present utility model, according to different race, sex, age, height, bone length design, can be straight plate or plate two ends (or one end) is designed to anatomic form shape according to the anatomic form feature of femur, tibia, fibula, humerus, ulna, radius, metacarpal bone, phalanges, metatarsal, phalanx, clavicle.
The utility model has the advantage of for closed fracture, belong to Minimally Invasive Surgery, only to fracture Limited exposure or need not cut the reset of percutaneous clamp, fracture two ends only need percutaneous to hole, put and follow closely, in guarantee under the effectively fixing prerequisite of fracture, reduce damage to soft tissue, postoperative to leave over cicatrix little, plays beautification function.For compound fracture, fixedly change for internal fixtion two operations after soft tissue covers relative to first traditional external fixer, this utility model once can be performed the operation and just can be completed the replacement and fixation of the long and short bone fracture of extremity, can work as external fixer uses (the same with external fixer, while fixing, do not affect VSD vacuum suction, the operations such as transfer of skin flap), also can change internal fixtion and can effectively ensure fracture healing.No matter be closed or compound fracture, after patients with fractures's healing, need not be in hospital, can extenal fixation be removed without the need to anesthesia, not need second operation, reduce health care costs, alleviate patient suffering.Locking extenal fixation frame plate of the present utility model can be used for temporary fixed, also can be used for long-time fixing, takes off after union of fracture.
